Vitex trifolia

Vitex trifolia is a large coastal shrub or small tree, up to 8 m (26 ft) in height and a trunk up to 20 cm (7.9 in) diameter. The leaves are oppositely arranged along the stems and are usually compound, composed of three or five leaflets. The central leaflets may grow up to 12 cm (4.7 in) long and 4 cm (1.6 in) wide, and the lateral leaflets may be 5 cm (2.0 in) long and 2 cm (0.79 in) wide. The upper surfaces of the leaves are green and the lower surfaces are grayish green.^[5][6]

The flowers are born in panicles or clusters up to 25 cm (10 in) in length. Individual flowers have mauve or purple, five-lobed corolla tubes that are about 5 mm (0.20 in) long and 3 mm (0.12 in) wide; they are finely hairy outside and have a dense patch of longer hairs in the mouth of the tube. The stamens are 3–6 mm (0.12–0.24 in) long, and the ovary is globular and about 1.5 mm (0.06 in) diameter. The fleshy fruits are up to 6 mm (0.24 in) in diameter and contain four small seeds.^[5][6]

Two varieties are recognised as of April 2026^[update], Vitex trifolia var. taihangensis and the autonym Vitex trifolia var. trifolia.^[2]

Vitex trifolia naturally occurs close to coasts in beach forest and the landward side of mangrove swamps, usually below 150 m (490 ft) altitude.^[5][6]

The species is classed as least concern by the International Union for Conservation of Nature (IUCN). The reason for this assessment is that the plant is widely distributed and also widely cultivated, and despite some loss of habitat it is thought to be not under any threat.^[1]

In Samoa it is used to relieve fever, exhaustion, asthma, headache and rashes.^[8] In Fiji a poultice of the leaves is used to treat broken bones and abrasions; in the Solomon Islands the leaves are used as a treatment for headache; on Bougainville it is used as a laxative; in Truk the leaves are made into a tea to treat itching skin.^[6]
